This species is known only from the type locality in the Corbett's Gap region, in the Knuckles range of central Sri Lanka, at an altitude of 1,245m asl (Meegaskumbura and Manamendra-Arachchi 2005). There is also a recent record from the nearby Bambarella Peak (M. Meegaskumbura pers. comm.). It may occur in other cloud forests of the Knuckles Hills, but further survey work is needed to confirm this
Habitat and Ecology
It is found in shrubs in gaps within closed-canopy montane cloud forests, as well as cardamom plantations within the forest. However, it has only been observed in or very close to relatively undisturbed forest, though it seems to do well in forest gap areas such as those created by selective logging. Males usually call from vegetation 0.3-1m above the ground. The diurnal resting habitat of these frogs is under a leaf, or on a leaf axil, often in well-illuminated habitats (Meegaskumbura and Manamendra-Arachchi 2005). It is presumably a direct developer like other species in the genus.
It is found in low abundance.
The major threat is clearing of the species' forest habitat, due to subsistence agriculture and logging. Drought is also an important threat.
Bambarella Peak is part of the Knuckles Forest Reserve, but Corbett's Gap is not currently known to fall in any protected area, and is in need of urgent habitat protection. Further survey work is needed to better determine the distribution range of this species, and its current population status.
